Egg Osmosis: A four day eggsperience!

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days. Through the process of osmosis, water passes through the egg membrane to make the egg swell (in the water) or make the egg shrink (in the corn syrup). This activity, located on page 2 of the PDF, is a take-home version of the display of the same name in the Biochemistry unit in OMSI's Chemistry Lab. Also included on the PDF are two additional activities: Yeast Balloons and Cabbage Juice Indicator.
